Fuel Gauge for PCB of 25.9V Li-Ion Battery Pack (#4482)
Note: This fuel gauge is not intend to be use as a very accurate reading of the battery pack's capacity. The battery level indication can vary by 5% depending on the capacity of the pack!
Features
- Apply to PCB/PCM of 7 cells Li-ion / Polymer Li-ion 25.9V battery pack.
- No external power is need
- Can connect directly to pcb/pcm via special connector on board or connect directly to output of battery pack
- 5 LEDs display battery pack's voltage. The voltage listed below is base on battery during discharge. (The actual voltage might vary for LED 2-4 during charging.)
- 1 LED Flashing = pack voltage < 20.4V (must recharge battery)
- 1 LED = pack voltage: 20.3-24.6V (battery need recharging)
- 2 LED = pack voltage: 24.5-26.1V
- 3 LED = pack voltage: 26.0-27.1V
- 4 LED = pack voltage: 26.9-27.9V
- 5 LED = pack voltage: 27.8V or higher ( battery is fully charge)
Specifications
- Power consumption: Max 2mA
- Dimension (LxWxH): 51mm x 26mm x 4mm
